Wyckoff Accumulation Schematic Explained: Phases A to E
Lesson 3 of 8 · Intermediate
What is accumulation and where does it form?
Accumulation is a trading range that forms after a downtrend, during which large buyers gradually absorb the available supply. The Wyckoff schematic is an idealised map, not a template the market is obliged to follow. It is divided into five phases, A to E, and each key event has a short English label. There are two common variants: accumulation with a Spring, and accumulation in which price never trades below the range low and Phase C appears as a higher low.
Phase A: stopping the downtrend (PS, SC, AR, ST)
- PS (Preliminary Support): the first notable buying after a long decline; volume and range increase and the pace of the fall slows, but the trend usually still continues.
- SC (Selling Climax): emotional selling with a very wide range and very high volume. The candle often closes well above its low, because large buyers absorb the panic selling.
- AR (Automatic Rally): a sharp bounce after the SC as selling pressure runs out and shorts cover. The AR high marks the upper boundary of the range.
- ST (Secondary Test): a return to the SC area to test the remaining supply. Ideally it comes on lower volume and a narrower range than the SC; the ST may finish slightly above or below the SC low.
Hypothetical example: gold has fallen from 4,150 dollars. Volume rises around 4,010 (PS), then a sharp sell-off to 3,980 on exceptional volume closes off the low (SC). The bounce that follows reaches 4,045 (AR), and a few days later price returns to 3,990 on lower volume (ST). All numbers are for illustration.
Phase B: building the cause
Phase B is usually the longest part of accumulation. Price swings between the AR high and the SC low while big players build positions in between. We may see several more STs, and sometimes price pokes slightly above the range top and returns. Signs that demand is strengthening during Phase B:
- volume on down-swings gradually shrinks;
- up-swings show better range and volume;
- lows hold, or price dips only slightly and on low volume below them.
Most misleading swings occur in this phase, and its duration is the "cause" that we measure with Point & Figure in a later lesson.
Phase C: Spring, Shakeout and Test
Spring: a penetration of the range support (the SC low and the STs) followed by a quick return inside the range. Its job is to test the remaining supply and to collect liquidity from the stop-losses resting below the lows. If the poke comes on low volume, little supply remains; if it comes on high volume, a later test is usually needed. A Shakeout is a sharper, deeper version of the same event.
Test: a return to the Spring area on lower volume and a narrower range, with the Spring low holding. A successful test suggests sellers can no longer push price lower.
Hypothetical example: price drops to 3,972 dollars, below the SC low of 3,980, and returns above 3,985 in the same session. The next day a pullback to 3,982 comes on roughly half the Spring's volume, and the low holds. Remember that not every accumulation has a Spring.
Phases D and E: SOS, LPS, BU and leaving the range
| Event | Definition | Expected volume behaviour |
| SOS (Sign of Strength) | A rally that reaches or crosses the top of the range or the resistance line (the Creek) | Wide range and rising volume |
| LPS (Last Point of Support) | A pullback after the SOS that forms a higher low; may repeat several times | Low volume and a narrow range |
| BU (Back-Up) | A return to the broken resistance, now acting as support; often coincides with an LPS | Declining volume on the pullback |
A decisive break through the Creek is sometimes called a "jump across the Creek" (JAC). In Phase E price leaves the range and enters markup; smaller ranges along the way may be re-accumulation.
When does the pattern fail?
- The Spring does not return: if price stays below the low, volume grows on the decline and bounces are weak, the range was probably re-distribution or merely a pause within the downtrend.
- The SOS does not hold: a push through the Creek on high volume followed by a quick return into the range weakens the accumulation hypothesis.
- Labelling after the fact: phases usually become clear only later; in real time, think in probabilities.
- Major news: a CPI-type data spike can create Spring-like pokes that have nothing to do with absorbing supply.
Common mistakes
- Expecting a Spring in every accumulation and ignoring the version without one
- Calling every break of the low a Spring before price has returned inside the range
- Rushing to label Phase B and Phase D while the range is still incomplete
- Ignoring volume in the ST and Test; a heavy-volume test means something different
- Setting the invalidation level after entering instead of before
What does volume say here?
Order flow makes the accumulation events easier to measure. In a genuine Spring we often see heavily negative delta below the range low while price fails to progress, and the footprint shows large resting buy volume at several of the lower prices: absorption. At the SC, a volume profile usually builds a high-volume node near the bottom of the range. At the SOS, sustained positive delta together with acceptance above the Creek shows effort and result in agreement.
Even so, absorption can be temporary and resting limit orders can be pulled. An order-flow signal is worth something only when it occurs at the right place in the structure and price confirms it afterwards.

Frequently asked questions
Does every accumulation have a Spring?
No. In many ranges price never goes below the low and Phase C appears as a higher, low-volume low. Waiting for a Spring can sometimes make you miss the whole structure.
What is the difference between a Spring and a genuine break of the low?
In a Spring, price returns quickly inside the range and is not accepted below the low. In a genuine break, price stays below the low, volume increases on the decline and bounces are weak.
How long does Phase B usually last?
There is no fixed rule. Phase B is the longest phase on any timeframe; it may take weeks on a daily chart and a few hours on a five-minute chart.
